Subject: NANFA-- Re: PNW minnows in aquaria
Thanks, Norm.
I've always wondered if the chiselmouth adapted to aquarium life considering
their specialized feeding strategy. Interestingly, it's not the algae
they're
after. Instead, they feed on the diatoms and microcrustaceans that live
within
the algae. Very little of the algae they eat is actually digested.
Do you have any photos of chisel- or peamouth in the aquarium? Might make
for a
nice article.
